"We are witnessing a precipitous drop in the price delta for Smart TVs compared to their traditional counterparts, reflecting the expectation of major TV vendors that they will make more money down the road from content partnerships rather than upfront on higher hardware costs. Though it remains to be seen how quickly this scenario will materialize, the immediate need for Over-the-Top content on Ultra HD TVs may be a catalyst," said David Watkins, Director of Connected Home Devices at Strategy Analytics.
